Description

Technical Field

[0001] This utility model relates to the field of circuit connection, and more particularly to a power supply terminal used in photovoltaic equipment. Background Technology

[0002] Terminals can be used for power supply and signal transmission. A power supply terminal is an interface device used to connect power sources and electronic devices. Its main function is to transmit power to electronic devices, thereby providing driving power for the electronic devices. With the continuous development of electronic science and technology, more and more electronic devices are widely used in various fields of people's daily production and life.

[0003] Photovoltaic systems are exposed to the outdoor environment for extended periods, so the terminal connections must withstand mechanical stresses such as vibration, wind load, installation deformation, and snow pressure. Traditional terminals do not have specific stress relief designs, resulting in short connection structures and poor stress relief capabilities. Long-term mechanical stress can lead to connection structure breakage, and replacement costs are very high.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a terminal connection structure that is resistant to stress and fatigue for photovoltaic applications.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0029] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0031] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0032] The accompanying drawings illustrate various structural schematic diagrams according to embodiments disclosed in this invention. These drawings are not to scale, and some details have been enlarged for clarity, and some details may have been omitted. The shapes of the various regions and layers shown in the drawings, as well as their relative sizes and positional relationships, are merely exemplary and may deviate from reality due to manufacturing tolerances or technical limitations. Furthermore, those skilled in the art can design regions / layers with different shapes, sizes, and relative positions as needed.

[0033] like Figures 1 to 4 As shown, the photovoltaic application stress- and fatigue-resistant power supply terminal of this utility model includes a terminal body 1 and a crown spring 2. The crown spring 2 is disposed within the terminal body 1.

[0034] like Figure 1 As shown, the terminal body 1 consists of a socket connector 101, a buffer structure 102, and an assembly connector 103. The socket connector 101 is connected to the front end of the buffer structure 102, and the assembly connector 103 is connected to the rear end of the buffer structure 102.

[0035] The front end of the socket connector 101 is provided with a socket opening 1011, and the rear end is connected to the buffer structure 102. The crown spring 2 is assembled on the inner wall of the socket connector 101 near the socket opening. The power plug can be inserted into the socket opening 1011 and contact the crown spring 2.

[0036] like Figures 1 to 4 As shown, the outer front end of the socket connector 101 is stamped at an angle 104, thereby improving the smoothness of the socket connector 101 during insertion.

[0037] Furthermore, since the outer side of the front end of the socket connector 101 is stamped into an angle 104, and the front end material is folded inward, a stop boss 113 will be formed on the inner wall of the socket connector 101. The stop boss 113 can prevent the crown spring 2 inside the terminal body 1 from sliding out of the socket opening 1011.

[0038] like Figures 1 to 4 As shown, multiple limiting springs are stamped out on the side wall of the socket connector 101, including an inwardly folded spring 105 and an outwardly folded spring 106.

[0039] The inner folding spring 105 is disposed between the crown spring 2 and the buffer structure 102, and protrudes into the interior of the insertion connector 101 to prevent the crown spring 2 inside the terminal body 1 from sliding backward. The inner folding spring 105 and the stop boss 113 are located at the front and rear ends of the crown spring 2 respectively, thereby completely limiting the movement of the crown spring 2.

[0040] The outward-facing spring 106 is located near the front end of the socket connector 101, which can prevent the terminal body 1 from sliding out towards the assembly connector 103 after the terminal body 1 is assembled into the terminal housing (not shown in the figure).

[0041] like Figures 1 to 4 As shown, the outer wall of the socket connector 101 has a stamped guide rib 112 near the buffer structure 102. The guide rib 112 will align with the guide groove of the terminal housing to ensure that the socket connector 101 is at a uniform angle when assembled into the housing.

[0042] like Figures 1 to 4 As shown, multiple locking protrusions 111 are stamped out on the outer wall near the socket connector 101. The locking protrusions 111 surround the rear end of the socket connector 101. By controlling the height of the locking protrusions 111, the socket connector 101 can be prevented from shaking inside the housing.

[0043] In a preferred embodiment of this utility model, the socket connector 101 is a hollow cylinder formed by stamping.

[0044] like Figures 1 to 4 As shown, the buffer structure 102 is designed with a bent portion 1021. Preferably, the buffer structure 102 has a sheet-like, wave-shaped design, similar to a spring, which can effectively alleviate the impact force transmitted from the front-end socket connector 101 and release stress.

[0045] Furthermore, the wave-shaped design of the buffer structure 102 increases the arc length, providing a longer arc length to distribute the deformation and prevent excessive stress concentration in the event of lateral impact.

[0046] More preferably, a long strip opening 1022 is stamped in the middle region of the buffer structure 102. The opening 1022 divides the wave-shaped connector 102 into two pieces. The two independent pieces design can improve the flexibility of the connecting pieces and release more lateral impact force than the whole piece design, resulting in better stress release effect.

[0047] like Figures 1 to 4 As shown, the surface of the assembly connector 103 is stamped with a large number of evenly distributed grooves 1030. After the assembly connector 103 is assembled onto the circuit board, spot welding will be performed to achieve conductivity and ensure firmness. The grooves 1030 increase the welding area, which can better hold the solder after welding and increase the welding holding force.

[0048] like Figures 1 to 4As shown, the assembly connector 103 includes a head 1031 and a tail 1032. The head 1031 is conical, which facilitates the assembly connector 103 being assembled into the circular hole of the circuit board. The tail 1032 is provided with a folded edge 1033, which ensures that the assembly connector 103 is at the same depth when mounted on the PBCA circuit board.

[0049] In use, the power plug is inserted into the socket opening 1011 to contact the crown spring 2. The assembly connector 103 is used to assemble into the solder hole of the circuit board, and then spot welded to the PCBA circuit board of the photovoltaic equipment to realize the power supply to the photovoltaic equipment.

[0050] The power supply terminal disclosed in this utility model increases the stress release area through the design of the buffer structure 102, which solves the problem that the current photovoltaic terminals have weak stress release effect under constant vibration, wind load, installation deformation, snow pressure and temperature fluctuations, and are prone to fatigue fracture, thus reducing unnecessary economic losses for users.

[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0052] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
